Answer:

a. y = 1.5x

Step-by-step explanation:

Both equations are equations of a line. All options have the form:

y = a*x

where y and x are the variables and a is the slope.

The slope of the equation corresponding to machine B is less than the machine A's slope (machine A line is above machine B line). The only option in which the slope is less than 3 is y = 1.5*x.

The correct answer is y = 1.5x, A.
I am sure it is because I took the K12 test. I used the answer from the other person that answered this, and got it wrong. I reviewed the test, and It says that 1.5x is correct.

Miguel bikes 23 km per hour and starts at mile 10. Gabby bikes 28 km per hour and starts at hour 0. Which system of linear equat

Goshia [24]

Answer:

Miguel: d = 23t + 10

Gabby: d = 28t

Step-by-step explanation:

We can write the equation for each case in slope-intercept form, d = mt + b

Where,

d = total distance

t = time

m (rate) = distance/hr

b = initial value

✔️ Miguel:

m = 23 km/hr

b = 10 mile

Equation: subtitle the values into d = mt + b

d = 23t + 10

✔️ Gabby:

m = 28 km/hr

b = 0 mile

Equation: subtitle the values into d = mt + b

d = 28t + 0

d = 28t

Which situation is represented by this equation?

navik [9.2K]

No less than or greater than signs are used, so C and D are out

In this case the equation starts as .45M + 3.50

The only matching statement is A

Q # 15 please Graph the equation .y = 4x - 3

murzikaleks [220]

Answer: Please, see the attached file.

Thanks.

Solution:

We can graph using the intercepts:

(1) y-intercept, when x=0

y=4x-3→y=4(0)-3→y=0-3→y=-3

Point=(x,y)=(0,-3)

(2) x-intercept, when y=0

y=4x-3→0=4x-3

Solving for x: Adding 3 both sides of the equation:

0+3=4x-3+3

3=4x

Dividing both sides of the equation by 4:

3/4=4x/4

3/4=x

x=3/4=0.75

Point=(x,y)=(3/4,0)=(0.75,0)

With these pair of points (0, -3) and (0.75,0) we can draw the right line
